The main advantage of shell moulding
is that
A metallic pattern is used
The moulds are stronger
Thin sections can be easily obtained
Highly complex sections can be easily
obtained
Thin sections can be easily obtained
Shell moulding : Shell moulding is an
expandable mould casting process that uses resin covered sand to form the mould.It
is used for small to medium parts that require high precision.
Advantages of shell moulding :
1. Better dimensional accuracy
2. Higher production rate and lower
labour requirement
3. Good for thin and complex casting
Hence, the correct option is (C).
